Hm? DNS completely separates IPv4 and IPv6 addresses; they're different
record types ("A" versus "AAAA") in the DNS "database".

And the "interoperation" if IPv4 and IPv6 is pretty much not happening,
if you're talking about the compatability addresses. I won't get into
all the reasons why.

All that said, I'm not advocating separating (or not separating)
IPv4 and IPv6 addresses. I'm still undecided on the issue. I can see
situations where I might want to store both together, but then again, I
can see situations where I certainly wouldn't.

Perhaps we should think about another example to try to illuminate this:
what about storing ISO/OSI addresses in the same type as well? Isn't
that just the same thing as storing IPv4 and IPv6 addresses together?
